JOU RNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 432,156, dated July 15, 1890.

Application filed April 24, 1890. Serial No. 349,329. (No model.)

To @ZZ whom t may concern:

De it known that I, ANDREW DINGWALLI COX, a citizen of the United States, residing at IVestVinchester, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Journal-Boxes; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in journallboxesof that class which are provided with'an oil-chamber in the lower portion of the box and with a peripheral groove adapted to receive a collar secured to the shaft, by means of which collar and its attachments the oil is taken up and distributed upon the face of the shaft. I also provide conduits for the oil, so that the surplus oi'l shall iind its way back into the oilchamber, and thus prevent waste. By my construction, as hereinafter described, I provide a journal-box which is self-oiling and which may be used in any temperature and with all grades of oil.

To these ends and to such others as the invention may pertain the same consists in the peculiar construction and in the novel combination, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then spe' citically defined in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which drawings- Figure 1 is a perspective view of a journalbox constructed in accordance with my invention. Fig. 2 is a central longitudinal section of the same. Fig. 3 is `a transverse section upon the line 0c c of 2. Fig. 4 is a section upon the line @j y of Fig. 2.

Reference now being had to the details of the drawings by letter, A is a journal-box, which is cylindrical in form and is provided upon its upper face at its longitudinal center with a raised portion A', for the accommo dation of the oil-feeder, hereinafter described, and which'extension with the lug A2 upon the lower face of the journal-box serve as bearings for the screws C or other means for attaching the box to the hangers.

B is a casting, which forms the bearing for the lower portion of the shaft, which casting is provided upon `its sides with shoulders l), which rest upon c `rresponding shoulders b', formed in the j ournal-boX A for that purpose. Between said journal-box and the casting B is provided a suitable oil-chamber b2, which extends substantially the entire length of the j ournal-box.

C is a casting, which forms the bearing for the upper portion of the shaft, and is fitted into the journal-box A in the same manner as the corresponding casting B. The said castings B and C are each formed in two pieces, as will be seen, so that one may be placed upon each side of the central peripheral groove d', as will hereinafter be described.

D is the oil-feeder, which consists of a collar of metaldivided into two sections, which are provided at their ends with means whereby the sections may be united. In the present inst-ance I have shown the ends as provided with ears d, through which a pin or screw may be passed to secure them together. This collar is fitted upon the shaft and is adapted to rotate there with within a peripheral groove d', formed in the inner face of the journalbox. The manner of attaching the collar to the shaft is as follows: I cut away the inner face of the collar upon its opposite sides, and in one of the recesses thus formed I place a piece of leather d? and in the other recess a fiat spring` d3, as shown. The spring is adapted to bear against the shaft and thus serve to hold the collar in place with a sufficient degree of firmness to cause the same to revolve with the shaft, and yet permit such lateral movement thereon as may be necessary in order to accommodate itself to the changes that may be necessary by the expansion or contraction of the shaft.

The collar D is provided upon its outer face with a series of inclined or curved wings or arms d4, which are adapted to take up the oil from the oil-chamber in the lower portion of the journalbox, and the inclined slots E,

IOO

which are provided within the inner face of the box-lining, serve to cause the oil that is thus carried upward to be evenly distributed upon the surface of the shaft, and also insures the return of the surplus oil to the oil-chamber, thus preventing possible waste. IVhile I have shown but a single feeder in connection with the journal-box illustrated in the drawings, it is at once evident that in case the box were long two or more of these collars could be used, if desired.

F is anv arm extending horizontally from the lower portion of the journal-box. This extension is provided with a horizontal aperture F', communicating at its inner end with the interior of the oil-chamber in the journal-box, and at its outer endis provided with a suitable relnovable stopple f, which may be removed when it may be neceesary to clean or remove the oil from the chamber. A vertical aperture f', near the outer end of the extension and communicating with the opening F, is utilized for filling the oil-chamber, and as the entrance of the aperture f is upon a higher level than the top of the oil-chamber it will readily be seen that by keeping the same illed with oil the said chamber will be supplied and that the amount of oil within the chamber may be at any time determined by noting the height of the oil within the aperture.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

The combination, with the box and its lining formed with inclined oilways E, of the castings, the horizontal arm F, extending from the lower portion of the box and having horizontal passage F', vertical aperture f', and removable stopple f, the oil-chamber and the oil-feeder formed with curved arms d4, the washer d2, and the Iiat spring d3.

In testimony whereof I affix my signature in presence of two Witnesses.
